Installation

Setup

!!! danger

Do **not** expect this project to work correctly on your desktop if your Desktop Environment (DE) and Display Manager (DM) are not supported. Your DE/DM might not load, and that would be a **feature**.

Due to the development stage of this project, the default package configuration installs all profiles in complain mode. The recommended installation workflow is as-follow:

  1. Configure AppArmor AppArmor for apparmor.d.
  2. Install apparmor.d in the (default) complain mode.
  3. Configure your personal directories.
  4. Reboot your system.
  5. You must check for any AppArmor logs with aa-log.
  6. Report any raised logs.
  7. Use the profiles in complain mode for a while (a week), regularly check for new AppArmor logs.
  8. Only if there are no logs raised for your daily usage, install it in enforce mode.

Requirements

AppArmor

An AppArmor supported Linux distribution is required. The default profiles and abstractions shipped with AppArmor must be installed.

Desktop environment

The following desktop environments are supported:

  • :material-gnome: Gnome (GDM)
  • :simple-kde: KDE (SDDM)
  • :simple-xfce: XFCE (Lightdm) (work in progress)

Build dependency

  • Go >= 1.21

Configure AppArmor

As there are a lot of rules (~80k lines), it is recommended to enable fast caching compression of AppArmor profiles. In /etc/apparmor/parser.conf, add write-cache and Optimize=compress-fast:

echo 'write-cache' | sudo tee -a /etc/apparmor/parser.conf
echo 'Optimize=compress-fast' | sudo tee -a /etc/apparmor/parser.conf

Installation

=== ":material-arch: Archlinux"

`apparmor.d-git` is available in the [Arch User Repository][aur]:

```sh
yay -S apparmor.d-git  # or your preferred AUR install method
```

Or without an AUR helper:

```sh
git clone https://aur.archlinux.org/apparmor.d-git.git
cd apparmor.d-git
makepkg -si
```

=== ":material-ubuntu: Ubuntu"

Build the package from sources:

```sh
sudo apt install apparmor-profiles build-essential config-package-dev debhelper golang-go rsync git
git clone https://github.com/roddhjav/apparmor.d.git
cd apparmor.d
dpkg-buildpackage -b -d --no-sign
sudo dpkg -i ../apparmor.d_*.deb
```

!!! tip

    If you have `devscripts` installed, you can use the one liner:

    ```sh
    make dpkg
    ```

!!! warning

    **Beware**: do not install a `.deb` made for Debian on Ubuntu, the packages are different.

    If your distribution is based on Ubuntu, you may want to manually set the target distribution by exporting `DISTRIBUTION=ubuntu`.

=== ":material-debian: Debian"

Build the package from sources:

```sh
sudo apt install apparmor-profiles build-essential config-package-dev debhelper golang-go rsync git
git clone https://github.com/roddhjav/apparmor.d.git
cd apparmor.d
dpkg-buildpackage -b -d --no-sign
sudo dpkg -i ../apparmor.d_*.deb
```

!!! tip

    If you have `devscripts` installed, you can use the one liner:

    ```sh
    make dpkg
    ```

!!! note

    You may need golang from the backports repository to build:

    ```sh
    echo 'deb http://deb.debian.org/debian bookworm-backports main contrib non-free' | sudo tee -a /etc/apt/sources.list
    sudo apt update
    sudo apt install -t bookworm-backports golang-go
    ```

!!! warning

    **Beware**: do not install a `.deb` made for Ubuntu on Debian, the packages are different.

    If your distribution is based on Debian, you may want to manually set the target distribution by exporting `DISTRIBUTION=debian`.

=== ":simple-suse: openSUSE"

openSUSE users need to add [cboltz](https://en.opensuse.org/User:Cboltz) repo on OBS:

```sh
zypper addrepo https://download.opensuse.org/repositories/home:cboltz/openSUSE_Factory/home:cboltz.repo
zypper refresh
zypper install apparmor.d
```

=== ":material-home: Partial"

For test purposes, you can install specific profiles with the following commands. Abstractions, tunable, and most of the OS dependent post-processing is managed.

```sh
make
sudo make profile-names...
```

!!! warning

    Partial installation is discouraged because profile dependencies are not fetched. To prevent some AppArmor issues, the dependencies are automatically switched to unconfined (`rPx` -> `rPUx`). The installation process warns on the missing profiles so that you can easily install them if desired. (PR is welcome see [#77](https://github.com/roddhjav/apparmor.d/issues/77))

    For instance, `sudo make pass` gives:
    ```sh
    Warning: profile dependencies fallback to unconfined.
    @{bin}/wl-{copy,paste} rPx,
    @{bin}/xclip           rPx,
    @{bin}/python3.@{int} rPx -> pass-import,  # pass-import
        @{pager_path}        rPx -> child-pager,
    '.build/apparmor.d/pass' -> '/etc/apparmor.d/pass'
    ```
    So, you can install the additional profiles `wl-copy`, `xclip`, `pass-import`, and `child-pager` if desired.

Next: Configure your personal directories{ .md-button .md-button--primary }

Uninstallation

=== ":material-arch: Archlinux"

```sh
sudo pacman -R apparmor.d
```

=== ":material-ubuntu: Ubuntu"

```sh
sudo apt purge apparmor.d
```

=== ":material-debian: Debian"

```sh
sudo apt purge apparmor.d
```

=== ":simple-suse: openSUSE"

```sh
sudo zypper remove apparmor.d
```
